Application June 6, 1940, Serial No. 339,157 3 Claims. I.(c1. 242-845) This invention relates to fishing reels and more particularly to a device fastened to the frame of the reel for the purpose of automatically preventing backlash of the fishing line as the line is cast. I

Among the objects of the present invention is to provide an anti-backlash attachment for fishing substantially on the lines 3-3 and 4-4 respectively of Figure 2.-

8, the resulting "click can be used to advantage in approximating the amount of spring tension adjustment being made.

Also in accordance with the present invention there is disposed about the barrel 5 a relatively f strong coil spring I 4 and one end of the spring I6 seats against an integral collar or flange [5 provided at the tapered end of the barrel 5 while pin in as shown.

From the description of the i it will be apparent that when the attachment is properly mounted on the reel frame E6 the plug I, in response to the action of spring 8, will have frictional bearing contact with the adjacent end the other end of said spring impinges against the plate ll of the reel spool indicated generally by v the reference numeral IE to arrest properly the Figure 5 is a detail sectional view taken substantially on the'line 5-5 of Figure 1'.

Figure 6 isv an elevational view of a tubular member forming part of the invention, and Figure 7 is a fragmentary topplan view illustrating a slightly modified form of the invention Figure 8 is a view of the tubular member used with that form of the invention shown in Figure .7.

Referring more in detail to the drawings it will be seen that the anti;-backlash attachment coznprises, essentially, a barrel or tubular member 5 which at one end is tapered as atG and has projectible through said end 6 thereof a plug 1 that is normally urged outwardly with respect to said end 6 of the barrel 5 through the medium of a relatively light coil spring 8 housed within the barrel as shown.

The barrel 5 is provided on diametrically opposite sides thereof with slots 9 elongated longitudinally of the barrel to accommodate a transverse pin ID that extends transversely through the barrel and against'which one end of the spring 8 rotation of the reel at the end of the cast thus preventing the undesired backlash that often takes place at this point. When it is desired to mount the deviceon the reel as shown in Figures 1 to 4 inclusive, there is provided a' substantially u-shaped bracket IS, the legs 20 of which intermediate'their respective ends are bent outwardly as shown and have their terminals engagedfwith two of the stay posts '2! of the reel as shown and welded or otherwise positively secured thereto so ,as'to extend from the reel radially and as illustrated.

At the bight or closed end, thereof the frame It is provided. with a threaded opening to receive an end of the barrel 5 as shown, andthreaded on thisend of the. barrel 5 into'cpntefct with the bightor closed end of the frame I9 is a nut 22. 1

As shown in Figure 4 the bight or closed end I of the frame or bracket 19 is provided with a re-' cess circumjacent theopening provided therein for the barrel 5, and seated in this recess is a washer 23.

When using the frame I9. formounting the device on the reel the spring I 4 is compressed sutficiently to insure the action of the spring ll 1 against the pin l 0 for urging the same into seated impinges. The other end of. the spring impinges plug 1 and is convoluted about an integral For adjusting tension of the spring 8 there is threadedly engaged with the barrel 5 a nut 12 against which the pin Ill impinges, and on the bottom side thereof the nut I2 is provided with a circular series oi notches I: as shown.- and ob viously as the. notched edge of'the; nut I 2 rides over the'pin I 0 in eflecting, by rotation of .the

pin I I extending inwardly from said inner end of the plug I. (See Fig. 4.)

engagement with opposed notches 13 in the-nut 12. After the installation has been made then the- .nut I2 is adjusted on the barrel 5 to the extent desired in order that the spring 8 will cause the plug 1 to maintain proper friction contact with the side flange I! of the spool I8 to the endthat the device will function properly and as intended. When it is-desired to mount the device at the side of the reel as suggested in Figure 7, the frame or bracket I9 is dispensed with and the end 6 01' the barrel I extended through an opening in the nut l2, an adjustment or the tension of spring side oi. the reel so that the plug 1 will be Ina-posivention thus far pin longitudinally inwardly of the barrel 5 instead of passing the pin laterally through the slots transversely to the barrel as would be the case where the. slots are closed at their ends, as for example as shown in Figure 6. In this latter case the barrel has its side parts pressed outwardly by the insertion of a suitable tool through the slots 9 so that the pin ll can be passed through the barrel to place the notches, shown in Figure 5, opposite the slots. Then the side portions of the barrel are pressed inward again to cause the side walls of the slots to engage the notches in the pin as shown in Figure 5.

It is thought that a clear understanding of the construction, utility, operation and advantages 0f an attachment of this character will be had without a. more detailed description thereof.

' It is also to be understood that while I have herein shown and described a preferred embodiment or the invention, it is in no wise intended to restrict the invention to the precise details of construction, combination and arrangement of elements as herein illustrated and described,

other than as may be required by the prior art and scope of the claims appended hereunto.

It will also be understood that among the advantages of an anti-backlash attachment involving the features of the present invention are: the attachment can be mounted on the reel of the fly rod at the side thereor opposite to the handle of the reel; that the device may be used as a replacement for the ratchet-clicking device now generally forming the part of such reel equipment; but-one hand need be employed in operating the fly rod fishing apparatus, and'that the paying out of the fishline can be accomplished in a more eflicient mannerand to the end that the desired length of the line may be paid out ing reeLa barrel adapted to be mounted on th frame of the reel. a plug having a sliding flt in i one end or the barrel and arranged to frlctionally contact the spool of the reel, said barrel having diametrically opposed slots elongated longitudinally thereof, a pinextending transversely through the barrel and having an intermediate portion engaging in said slots, a relatively light ,coil spring housed in the barrel and having one end impinging on said plug and a second end impinging against said pin, and a nut axially adjustableon the barrel exteriorly thereof and against which said pin abuts.

2. In an anti-backlash attachment for a fishing reel, a barrel adapted to be mounted on the frame of the reel, a plug having a sliding fit in one end of the barrel and arranged to irictionally contact the spool of the reel, said barrel having diametrically opposed slots elongated longitudinally thereof, .a pin extending transversely through the barrel and having an intermediate portion engaging in said slots, a relatively light coil spring housed in the barrel and having one end impinging on said plug and a second end impinging against said pin, and a nut axially adjustable on the barrel exteriorly thereof andagainst which said pin abuts, said barrel at the plug-equipped end thereof being provided with a little at a time and without the immediate and conscious attention of the fisherman.

A further advantage of this invention lies in the construction and use of the adjusting nut l2 which, by reason of the notches provided therein, and the engagement of the spring-pressed pin with said notches, provides for a substantial locking of the nut in the position to which moved, and against being casually or easily displaced.

Having thus described the invention what is claimed as new is:

1. In an anti-backlashattachment for a fishan external collar, and a relatively strong coil spring disposed exteriorly of the barrel and having one end impinging against said collar and a second end impinging against said pin, as and for the purpose specified. s

3. In an anti-backlash attachment for a fishing reel. a barrel adapted to be mounted on the frame of the reel, a plug having a sliding fit in one end of the barrel and arranged to frictionally contact the spool of the reel, said barrel having diametrically opposed slots elongated longitudinally thereof, a pin extending transversely through the barrel and having an intermediate portion engaging in said slots, a relatively light coil spring housed in the barrel and having one end impinging on said plug and a second end impinging against said pin, and a nut axially adjustable on the barrel exteriorly thereof and against which 'said pin abuts, said barrel at the plug-equipped end thereof being provided with an external collar, and a relatively strong coil spring disposed exteriorly of the barrel and having one end impinging against said collar and a second end impinging against said pin, and said nut having on the side thereof contacted by said pin a circular series of notches for cooperation with the pin to give a clicking" sound incidental to the ad- Justment of the nut on the barrel to facilitate determining approximately the amount of tension on said springs.
